Merge pull request #3693 from ReinUsesLisp/clean-samplers 
shader/texture: Support multiple unknown sampler properties
 5 years ago
ReinUsesLisp ddd82ef42b shader/memory_util: Deduplicate code 
Deduplicate code shared between vk_pipeline_cache and gl_shader_cache as
well as shader decoder code.

While we are at it, fix a bug in gl_shader_cache where compute shaders
had an start offset of a stage shader.

ReinUsesLisp bd8b9bbcee gl_shader_cache: Rework shader cache and remove post-specializations 
Instead of pre-specializing shaders and then post-specializing them,
drop the later and only "specialize" the shader while decoding it.

ReinUsesLisp 4e35177e23 shader_ir: Implement VOTE 
Implement VOTE using Nvidia's intrinsics. Documentation about these can
be found here
https://developer.nvidia.com/reading-between-threads-shader-intrinsics

Instead of using portable ARB instructions I opted to use Nvidia
intrinsics because these are the closest we have to how Tegra X1
hardware renders.

To stub VOTE on non-Nvidia drivers (including nouveau) this commit
simulates a GPU with a warp size of one, returning what is meaningful
for the instruction being emulated:

* anyThreadNV(value) -> value
* allThreadsNV(value) -> value
* allThreadsEqualNV(value) -> true

ballotARB, also known as "uint64_t(activeThreadsNV())", emits

VOTE.ANY Rd, PT, PT;

on nouveau's compiler. This doesn't match exactly to Nvidia's code

VOTE.ALL Rd, PT, PT;

Which is emulated with activeThreadsNV() by this commit. In theory this
shouldn't really matter since .ANY, .ALL and .EQ affect the predicates
(set to PT on those cases) and not the registers.

Lioncash 1109db86b7 video_core/shader/decode: Prevent sign-conversion warnings 
Makes it explicit that the conversions here are intentional.

Lioncash bebbdc2067 shader_ir: std::move Node instance where applicable 
These are std::shared_ptr instances underneath the hood, which means
copying them isn't as cheap as a regular pointer. Particularly so on
weakly-ordered systems.

This avoids atomic reference count increments and decrements where they
aren't necessary for the core set of operations.

ReinUsesLisp 06c4ce8645 shader: Decode SUST and implement backing image functionality 6 years ago
ReinUsesLisp bf4dfb3ad4 shader: Use shared_ptr to store nodes and move initialization to file 
Instead of having a vector of unique_ptr stored in a vector and
returning star pointers to this, use shared_ptr. While changing
initialization code, move it to a separate file when possible.

This is a first step to allow code analysis and node generation beyond
the ShaderIR class.

ReinUsesLisp 6a6fabea58 shader_ir: Pass decoded nodes as a whole instead of per basic blocks 
Some games call LDG at the top of a basic block, making the tracking
heuristic to fail. This commit lets the heuristic the decoded nodes as a
whole instead of per basic blocks.

This may lead to some false positives but allows it the heuristic to
track cases it previously couldn't.

Lioncash 3e1a9a45a6 shader/decode: Avoid a pessimizing std::move within DecodeRange() 
std::moveing a local variable in a return statement has the potential to
prevent copy elision from occurring, so this can just be converted into
a regular return.
